    Hi,

    what exactly is the locking /concurrency control mechanism used in
    NFS to prevent simultaneous updates in NFS ?

    There is no need. If the updates are simultaneous, then neither is
    "more recent" than the other. So it doesn't matter. It only matters if
    a less recent update overwrites a more recent update.

    Some systems have/had a lock daemon running, and the NFS
    implementations coordinated with them to ensure concurrency.
